To grant admission, IIMs administer the Common Admission Test, also known as the CAT.
While the CAT score is the primary criterion, IIMs also use interviews, group discussions, and written ability tests to evaluate candidates after the CAT. Aside from that, they consider the candidate's past academic record as well as work experience.
So, to gain admission to IIM Bangalore, the procedure would be as follows:
Begin preparing for the CAT.
Fill out the CAT application form in the provided window.
Attend the CAT and achieve a high percentile. (Something like 99.5 or higher)
If you are selected, you must attend their GDPI round and perform well.
If everything goes well, you will receive an admission call from IIM B.
According to my brother's suggestion, IIM Bangalore not only stresses your percentile score in CAT but at the same time also takes into consideration your previous performances.
You should at least score more than 90% in classes X and XII and 80% in your graduation. You should have work experience of 2 to 3 years and meanwhile, prepare for the CAT exam.
Your final admission will be based on the scores from CAT, WAT, and PI. So prepare yourself and aim to score higher than 90 in each segment. If you have work experience, it will take precedence.
